I have a need to hide a guid used for an index on a .cshtml so I can get model binding on controls dynamically added with ajax (it’s a long story) (that was a mouthful)
I had a hard time finding the value in the hidden field; as it turns out, you can just get it by the attribute on the Selenium element like this:
IWebElement hiddenIndex = driver.FindElement(By.Id("MyControlName_0__Index"));
var indexValueToUse = hiddenIndex.GetAttribute("value");
If a user comes to a page with dynamically loaded dropdownlists using the back button – use this to force the page to reload so the dynamic controls reload their content to initial state:
if (performance.navigation.type === 2) {
location.reload(true);
Here is a simple way to download a file to a .net user control from a newer MVC controller.
The Controller code:
public FileResult DownloadSweetFile()
{
var downloadDirectory = _appSettings.PathToFile;
var filePathAndName = Path.Combine(downloadDirectory, "MySweetFile.pdf");
var cd = new System.Net.Mime.ContentDisposition
{
FileName = "MySweetFile.pdf",
Inline = false, //NOTE: This forces always prompting the user to download, not open file in the browser
};
Response.AppendHeader("Content-Disposition", cd.ToString());
return File(filePathAndName, "application/pdf");
}
I used a button on the page to fire the javascript
button type="button" id="btnSweetDownload" onclick="downloadSweetFile();" Click here to download a Sweet File!
(I removed the button tag so this will show correctly)
And here is the javascript to use in the .ascx file:
function downloadSweetFile() {
var url = '/MyControllerName/DownloadSweetFile';
window.location = url;
};
